15. USING A DIRECT DRIVE MOTOR

15 - 5

15.3.1 Startup procedure

Start up the direct drive servo in the following procedure.

Absolute position detection system

Installation and wiring

Turn on the Z-phase pulse of the

direct drive motor by using the JOG

operation. (Notes 1 and 2)

Execute the magnetic pole detection. (Refer to section 15.3.2.) (Note 1)

Absolute position

detection system?

Incremental system

Can you manually turn

on the Z-phase pulse of the

direct drive motor?

Change the setting to disable the

magnetic pole detection.

(Refer to (2) of section 15.3.2.)

Turn on the Z-phase pulse of the

direct drive motor manually. (Note 3)

Turn the servo amplifier power

supply off and on again. (Note 2)

Positioning operation check using the test operation mode (Note 1)

Positioning operation check using the controller (Refer to section 15.3.3.)

Home position return operation (Refer to the controller manual used.)

Positioning operation

Yes

Perform this procedure once at startup.

Set [Pr. PA01]. (Refer to section 3.14.)

Note 1.

Use MR Configurator2.

For the absolute position detection system, always turn on the Z-phase pulse of the direct drive motor while the servo amplifier

power is on, and then turn the servo amplifier power supply off and on again. By turning off and on the power supply, the

absolute position becomes confirmed. Without this operation, the absolute position will not be regained properly, and a

warning will occur at the controller.

If the Z-phase pulse of the direct drive motor can be turned on manually, the Z-phase pulse does not have to be turned on by

the magnetic pole detection or the JOG operation.

For this operation, always connect the direct drive motor encoder and the servo amplifier, and turn on only the control power

supply of the servo amplifier (L11 and L21) (turn off the main circuit power supply L1, L2, and L3). Perform this operation by

considering the safety.

Perform the magnetic pole detection.

Z-phase pulse of the direct drive

motor is turned on manually.

Z-phase pulse of the direct drive motor

is turned on by the JOG operation.

Turn the servo amplifier power

off and on again. (Note 2)

(Refer to the manual of the controller.)
